How to File Taxes as a Retiree

Retirement changes your income, but it does not always make taxes simpler. Instead of one paycheck and one W-2, you may have Social Security, pension income, IRA withdrawals, 401(k) distributions, investment income, part-time work, or required minimum distributions.

In this guide, you’ll learn how to file taxes as a retiree, what forms to gather, how different retirement income may be taxed, and how to avoid surprises during filing season.

TL;DR: Quick Decision Guide

• If you receive Social Security → some of your benefits may be taxable depending on your other income.
• If you took money from a pension, IRA, 401(k), annuity, or retirement plan → look for Form 1099-R.
• If you have investment income → gather 1099-INT, 1099-DIV, 1099-B, and brokerage statements.
• If taxes were not withheld from retirement income → you may need estimated payments or updated withholding.
• If you are age 73 or older → review required minimum distribution rules carefully.

Step 1: Gather All Retirement Income Forms

Retirees often have more income forms than they expect. Before filing, gather every tax document connected to retirement, investments, benefits, and part-time work.

Common forms include:

Form	What It Usually Reports
SSA-1099	Social Security benefits
1099-R	Pensions, annuities, IRAs, 401(k)s, and other retirement distributions
W-2	Part-time or seasonal job wages
1099-INT	Bank interest
1099-DIV	Dividends and distributions
1099-B	Investment sales
1099-G	State tax refund or unemployment income
1099-SA	HSA distributions
1095-A	Marketplace health insurance coverage, if applicable
Schedule K-1	Partnership, estate, trust, or certain investment income

The IRS says Form 1099-R is used for designated distributions of $10 or more from pensions, annuities, retirement plans, IRAs, insurance contracts, survivor income benefit plans, and similar sources.

What to do:
Create a retirement tax folder and save every form before filing. Do not file when only one retirement form arrives if you expect others.

Step 2: Know Whether Social Security Is Taxable

Social Security benefits are not always fully tax-free. Depending on your overall income, part of your benefits may be taxable.

The IRS explains that Social Security may become taxable when half of your Social Security benefits plus your other gross income exceeds certain thresholds, including $25,000 for many single filers and $32,000 for married couples filing jointly.

Other income that may affect Social Security taxation can include:

• Pension income
• IRA withdrawals
• 401(k) distributions
• Wages
• Self-employment income
• Interest
• Dividends
• Capital gains
• Tax-exempt interest

What to do:
Use your SSA-1099 and all other income records to determine whether any Social Security benefits are taxable. Tax software or a tax professional can calculate this for you.

Smile Money Tip:
Social Security taxes are not based only on the benefit itself. Other income can make part of your Social Security taxable, so retirement withdrawals and investment income matter.

Step 3: Report Pension, IRA, and 401(k) Distributions

If you received money from a pension, annuity, IRA, 401(k), 403(b), 457 plan, or similar retirement account, you should usually receive Form 1099-R.

A 1099-R may show:

• Gross distribution
• Taxable amount
• Federal income tax withheld
• State tax withheld
• Distribution code
• IRA or retirement plan information

Not every retirement distribution is taxed the same way. Traditional IRA and pre-tax 401(k) withdrawals are often taxable. Roth IRA or Roth 401(k) qualified distributions may be tax-free if requirements are met. Rollovers may be non-taxable if handled correctly, but they still may be reported.

What to do:
Enter each 1099-R carefully. Pay attention to taxable amount, withholding, and distribution codes. If a rollover appears taxable when it should not be, stop and review before filing.

Step 4: Review Required Minimum Distributions

Required minimum distributions, or RMDs, are mandatory withdrawals from certain retirement accounts once you reach the required age. The rules can be costly if missed.

The IRS has reminded taxpayers who turned 73 in 2025 that they could delay their first RMD until April 1, 2026, but would also need to take a second RMD by December 31, 2026.

RMDs may apply to:

• Traditional IRAs
• SEP IRAs
• SIMPLE IRAs
• 401(k)s
• 403(b)s
• 457 plans
• Other tax-deferred retirement accounts

Roth IRAs generally do not require RMDs during the original owner’s lifetime, though inherited accounts can have different rules.

What to do:
If you are near or over RMD age, confirm your required withdrawals with your retirement account provider. Keep records of the amount withdrawn and taxes withheld.

Step 5: Check Withholding on Retirement Income

Retirement income may or may not have enough tax withheld. If too little is withheld, you may owe at filing time.

Review withholding on:

• Social Security benefits
• Pension payments
• IRA withdrawals
• 401(k) distributions
• Annuity payments
• Part-time wages
• Investment income
• RMDs

The IRS says earned wages are subject to withholding for income tax, Social Security tax, and Medicare tax even if the taxpayer receives Social Security benefits. It also reminds seniors to check withholdings as part of filing season readiness.

What to do:
If you owed more than expected last year, consider adjusting withholding from pensions, Social Security, IRA distributions, or part-time wages. Estimated tax payments may also help.

Step 6: Report Investment Income

Many retirees receive investment income from savings, brokerage accounts, CDs, bonds, dividends, mutual funds, ETFs, or stock sales.

You may receive:

• 1099-INT for interest
• 1099-DIV for dividends
• 1099-B for investment sales
• Consolidated brokerage tax statement
• Schedule K-1 for certain investments

Investment income can affect your taxable income and may also affect how much of your Social Security is taxable.

What to do:
Wait for final brokerage forms before filing. Brokerages may issue corrected forms, especially for funds, REITs, or more complex investments.

Step 7: Review Medicare, HSA, and Health-Related Forms

Retirement can change your healthcare tax picture. Medicare, HSAs, long-term care, and medical expenses may all matter depending on your situation.

Pay attention to:

• Medicare premiums
• HSA distributions
• Medical expense records
• Long-term care insurance premiums
• Marketplace coverage before Medicare
• Form 1095-A, if you had Marketplace coverage
• Form 1099-SA, if you used HSA funds

Once enrolled in Medicare, you generally can no longer contribute to an HSA, though you can still use existing HSA funds for qualified medical expenses.

What to do:
Keep healthcare records organized. If you had high medical expenses, check whether itemizing deductions makes sense.

---

Step 8: Consider the Standard Deduction and Senior Deduction Rules

Many retirees take the standard deduction, but your deduction amount may be different if you are 65 or older or blind.

Tax rules for seniors can change, so review the current year before filing. For the 2026 filing season, the IRS has highlighted senior-focused updates and resources, including new law changes affecting older taxpayers.

You may also want to compare itemizing if you had:

• High medical expenses
• Mortgage interest
• Property taxes
• Charitable contributions
• State and local taxes
• Long-term care expenses

What to do:
Let tax software or a preparer compare standard deduction and itemizing. Do not assume retirement automatically means one option is always better.

Step 9: Watch for State Taxes in Retirement

State tax treatment of retirement income can vary widely. Some states tax pensions, IRA withdrawals, 401(k) distributions, or Social Security. Others exclude some or all retirement income.

State tax rules matter if you:

• Moved after retirement
• Receive a public pension
• Receive income from more than one state
• Own property in another state
• Have rental income
• Split time between states
• Recently changed residency

What to do:
Check your state’s retirement income rules before filing. If you moved or split time between states, consider tax help.

Step 10: Know When to Get Tax Help

Some retiree returns are simple. Others are more complicated because income comes from many places.

Consider getting help if you have:

• Multiple 1099-R forms
• RMD questions
• Roth conversions
• Large investment sales
• Rental income
• K-1 income
• Multi-state residency
• Inherited retirement accounts
• Charitable distributions from IRAs
• Long-term care expenses
• A spouse who died during the year
• Back taxes or IRS notices

The IRS has a seniors and retirees resource page that directs taxpayers to tools for determining whether retirement income, pensions, IRAs, and Social Security are taxable.

What to do:
Use tax software if your return is straightforward. Get professional help when retirement income, withdrawals, state rules, or estate-related issues become complex.
